Title: Recorder of pcm sound signal
Inventor: HAYASHI SHIYUNEI
IPC: H04B14/04
Filed: 1983-07-11
Abstract: PURPOSE:To detect assuredly a burst error by detecting the state of a specific bit that has no change of the bit contents in a normal state among additional codes of the PCM sound signal data for the satellite television broadcast. CONSTITUTION:The digital signal sent from a demodulating circuit is supplied to an error correcting circuit 231 of a decoder 23 as well as to an extracting circuit 234 of sound control bit, i.e., a specific bit in the control code. The data undergone the correction of errors through the circuit 231 undergoes the error correction again through an error correcting circuit 232 and fed to a shift register 233. The sound control bit extracted by the circuit 234 is supplied to a majority decision circuit 235. When a burst type error is generated, 0 and 1 are stored at random to the circuit 235. A detecting circuit 237 shifts the data stored in the register toward the lower order side 233 in case the number of error bits exceeds a prescribed level. Thus the output level of the register 233 is lowered.

IPC: H05K3/34
Filed: 1992-05-19
Abstract: PURPOSE:To easily recognize the accurate position of an electronic parts on a printed wiring board which parts is mounted by using boder lines, by forming a two-dimensional lattice mosaic pattern corresponding with coordinate axes, which pattern is formed by recoating coating or multicolored coating of resist on the printed wiring board. CONSTITUTION:A printed wiring board is coated with resist forming a two-dimensional lattice mosaic pattern. For example, firstly the board 1 is coated with first resist 3a, and secondly is coated in checker with second resist 3b. By the multi-layered coating of the second resist 3b in checker, in the above manner, differences of the transparency and the lightness of the resist are generated between the part where the multi-layered coating is performed and the part where it is not performed, and clear boder lines can be formed. Hence the boder line of resist which is the nearest to a coordinate position signal written on the board periphery can be traced without error. Thereby uncertainty that the fulcrum on the parts position is obtained by the eye while tracing the coordinate axis is excluded, and the coordinate position can be quickly defined.
